GLOIBE-PROTECTOR.

To all whom it may concarn:

Be it known that I, ALDEN V. BRowN, a citizen of the United States,residing at Troy, in the county of Rensselaer and State of New York,have invented a new and useful Globe-Protector, of which the followingis a specification.

It is the object of this invention to provide a protector for fragileelements in illuf `ployed minating constructions, such, for instance, asthe mantles which are commonly employed upon gas burners.

One object of the invention is to provide a transparent protector of theclass above mentioned, which shall be so constructed that it will befree to eXpand, both longitudinally and transversely, when heated,without danger of breaking.

Another object of the invention is to improve the means wherebyprotectors of this type are commonly held in position.

With the above and other objects in view, the invention consists in thenovel construction and arrangement of parts hereinafter described,delineated in the drawings, and specifically claimed, it beingunderstood that changes, properly falling within the scope of what isclaimed, may be made, without departing from the spirit of theinvention.

Similar numerals of reference are emto denote corresponding` partsthroughout the several figures of the drawings.

In the drawings,-Figure 1 is a perspective, showing the device of myinvention mounted upon a gas burner of improved type; Fg. 2 is aperspective of the protector disassociated from the burner upon which itis ordinarily mounted; Fig. 3 is a longitudinal section of theprotector, parts being shown in elevation; and Fig. 4 is a top planthereof.

In the drawings, the numeral 1 denotes the gas pipe, to which is secureda ring 2, the same being held in place upon the pipe 1 by means of arms3, the ring 2 commonly carrying the globe portion of the gas lamp.

The device forming the subject matter of this application, may be used,either upon upright or inverted illuminating structures, the lnvertedtype being delineated in the present instance.

An annular member 4, is shown, preferably fashioned from a single stripof metal, and provided, at its upper edge, with a plurality of radiallydisposed, outstanding arms 1 such instance,

5, which, if desired, may be fashioned integrally with the annularmember 4. These arms 5 are adapted to be bent, at their extremities, toform hooks 6, which, engaging the ring 2, are operative to hold theprotector in position about the mantle 12 of the gas lamp. This annularmember 4 is preferably fashioned from metal, and, threaded into it,between. the arms 5, are headed set screws 7. These set-screws 7 areadapted to be advanced to engage the pipe 1, to serve, either alone, orin combination with the arms 5, to support the protector in place.

Located within the annular member 4, and secured thereto by means ofsolder, or in any other manner adapted to a like end, is a ring 8,provided with an integrally formed, depending fiange 9, the fiange 9 andthe annular member 4, defining a trough, adapted to receive a pluralityof transparent strips 10, preferably fashioned from glass, the troughformed by the members 9 and 4 being filled with cement, to hold thestrips 10 in place, the cement being indicated by the numeral 11. Thesestrips 10, when mounted in place, give to the protector, a tubular form,the meeting edges of the strips 10 being parallel, and spaced slightlyapart, as denoted by the numeral 14. Owing to the fact that the edges ofthe strips 10 are thus spaced apart, and parallel to one another, itwill be seen that when the device is heated, the several strips 10 willbe free to expand, not merely longitudinally, but transversely as well.It is to be understood that the spaces 14 which exist between themeeting edges of the strips 10, are but slight, the construction beingsuch that when the strips 10 are heated to the vdegree to which theywill ordinarily be raised by the heat emanating from common ordinary gasburners, the spaces 14 will be closed, Owing to the eX- pansion of thestrips 10; thus inclosing the gas burner completely, and shielding thesame against wind.

Obviously, if desired, the outer globe of the burner,-which is shown indotted line in Fig. 1, may be removed entirely, the protector properconstituting the sole shield for the inantle 12 of the burner.

In supporting the protector in place, the set-screws 7 may be reliedupon solely; or the arms 5 may constitute the sole supporting means;likewise, both the arms 5 and the set-screw 7 may be employed together.In

the set-screws 7 will be advanced to engage the pipe lr, the set screWsbeing` manipulated until the protector is spaced at an even distancefrom the periphery of the mantle 12; Whereupon the extremities of thearms 5 may be bent to form the hooks 6.

Having thus described the invention, What is claimed is A device of theclass described comprising a plurality of straight, transparent stripsdisposed to form an open ended Vreceptacle; means for engaging thestrips at one end only, Whereby the strips may have free lon gitudinalexpanson; the strips being` spaced apart slightly, and being` expansibleWhen 15 heated, to touch along their longitudinal edges; and means forsecnring the device to a burner.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature 20 in the presence of two Witnesses.
